Application June 9, 1941, Serial No. 397,169

This invention relates to plumbing fixtures and more especially to an improved toilet flush tank.

-An object of the invention is to provide a simple, practical, and elicient device of the character described.

Another object of the invention is to provide an improved and simplied flush tank mechanism for toilets.

A further object of the invention is to provide a toilet hush mechanism not requiring a rubber ball valve.

A further object of the invention is to provide a ush tank mechanism in which the customary iloat valve ball is eliminated.

Other objects and advantages will appear and be brought out more fully in the following specification, reference being had to the accompanying drawing, wherein:

Fig. l is a front perspective View partially broken away showing the embodiment of my invention;

Fig. 2 is a similar view showing the inner tank in the discharging position;

Fig. 3 is an enlarged elevation view, partly in section, of the valve, also shown in Figs. l and 2; and

Fig. 4 is a sectional view of the same.

Referring more particularly to the drawing, I show a toilet flush tank mechanism comprising the conventional water tank I, in which is positioned a tiltable pan A pivotally supported on a pair of brackets B within tank I. Pan A has a curved bottom as shown and the pivot support therefore is substantially along a radius of this curve and the pan is provided with an offset portion C, which, when the pan is filled with Water, the center of gravity would be to the right of the pivot axis as shown and the pan will remain in the normal position shown in Fig. 1. A rod or bar D extends across pan A and is adapted to engage the valve lever E of a pressure actuated valve F in the water supply line G which is supplied with a suitable nozzle H by which the pan is lled with water.

vA link K is pivotally connected to pan A as shown, and also to a rockarm L which has pivot bearing portion M which extends through the front of tank I and has a handle portion Q. The discharge outlet pipe is shown at R which extends about one inch above the bottom of tank I, and is provided with a small hole S through which the remaining water in the bottom of the tank I runs slowly in and lls pipe R, forming a hydro-static seal between the flush tank and the toilet bowl.

In Figs. 3 and 4 I show on an enlarged scale the pressure actuated valve F, having a valve body I, a plunger 2, provided with a seating member 3 which Seats on a valve seat 4. Valve lever E comprises a member 5 pivoted at 6, and provided with an arm 1 which is adjustably connected as by a wing screw 8 to member 5. Plunger 2 is provided with a groove 9 for engagement with the end portion I0 of member 5, by `which the plunger is pressed inwardly, closing valve 3 on seat 4 when rod D compresses against arm 1, thus closing the valve when pan A is lled. The wing screw 8 permits adjustment of the position of arm l so that the valve F can be closed at any desired level of water in the pan A.

The operation of the invention should be clear from the foregoing description. Pan A is tilted from the position in Fig. 1 to that of Fig. 2, and the water dumped therefrom into tank I when the rockarm L is rocked by the handle portion Q. From therelease oi the handle Q the pan A returns nearly to the position of Fig. l and starts filling with water from the valve F and nozzle H, however, until the Water raises and runs into offset portion C, there will not be suicient pressure from rod D on valve arm E to close valve F. However, this will occur when the pan is nearly full and is ready for another discharging operation.

It will be clear from the foregoing description that the above and otherv objects are attained by this invention, and it will be understood that changes and modifications may be made without departing from the spirit and scope of the subjoined claim, for instance, I may provide pan A so that it will rotate and dump forwardly instead of at the side.

Having described my invention, what I claim is:

A device of the character described, comprising a tank, a, pivoted rockarm in said tank, and having a handle portion externally thereof, a pair of brackets in said tank, a dump pan in said tank pivotaliy mounted on said brackets, a link connecting said pan and said rockarm, said pan having an ollset upper `portion at one side whereby to retain said pan, when lled, in an upright position, a rod extending between upper ,edge portions oi' said pan, a valve having a pressure actuated closing element and an adjustable actuating arm adapted to be engaged by said rod to close said valve when said pan is filled, said rockarm adapted to tilt said pan to discharge the contents thereof in said tank, said oset portion adapted to receive Water whereby to rock said pan to lirmly close said valve when said pan is filled.
